Check Digit Verification of cas no
The CAS Registry Mumber 102720-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,7,2 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 102720-74:
(8*1)+(7*0)+(6*2)+(5*7)+(4*2)+(3*0)+(2*7)+(1*4)=81
81 % 10 = 1
So 102720-74-1 is a valid CAS Registry Number.

Eiden, Fritz,Patzelt, Gertrud
, p. 242 - 251 (2007/10/02)
Starting with the compound 11, the isoxazole derivatives 22a and 27a are synthesized.These compounds are transformed to the substituted isoxazoles 23, 25 and 28.Catalytic hydrogenation of the isoxazol derivatives 11, 15 and 23 gives the 1,3,5-tricarbonyl
